Update PyQt to 4.11.1, QScintilla to 2.8.3 and SIP to 4.16.2.
... And bump PORTREVISION on ports that depend on devel/qscintilla2 due to
the shlib version change.
This is brought to you by the KDE on FreeBSD team. Besides updating to newer
upstream releases, this commit also contains a lot of under-the-hood changes
to the PyQt/QScintilla/SIP ports. Their Makefiles had accumulated a lot of
cruft over time, so it was time for some summer cleaning:
- General, belated changes:
* Use OPTIONS helpers wherever possible, stop including
<bsd.port.options.mk> when not necessary, stop checking for
${PORT_OPTIONS:MDOCS} and ${PORT_OPTIONS:MEXAMPLES} when not necessary,
add options such as DOCS and/or DEBUG where they were only checked for.

Update the KDE Software Compilation to 4.10.5.
Proudly brought to you by the KDE on FreeBSD team. We're sorry to ship two
KDE updates in just a few days, but the work on 4.10.5 was very light
compared to 4.10.4 so it was ready much faster.

The biggest news for us on FreeBSD is that the Ruby bindings should work
with Ruby 1.9 now.
I will probably add a note to UPDATING later about this, but as avilla@
pointed out, the clang support we mentioned that was improved in 4.10.4
requires a rebuild of the ports that depend on kdelibs4. Most of them are
covered by this update, but those which are not part of the Software
Compilation need to be rebuilt manually to make sure the previous issues
(proper symbol visibility being the most annoying of them) are solved.

Update to KDE SC 4.10.4, proudly presented by the KDE on FreeBSD team.
With commits from avilla@, makc@, rakuco@ and Schaich Alonso.

clang support should be more stable now, with clang being recognized by
kdelibs4 and being passed the correct flags to build other ports.
Additionally, all ports being committed have been verified to build with
-CURRENT's clang 3.3 on an amd64 tinderbox (special thanks go to swills@ for
providing it).
Work on the newly-released 4.10.5 will begin shortly.
